The aim of the lesson

To master the methodology of a comprehensive preventive examination and subsequent individualized lifestyle counselling to reduce the risk of disease in general and to prevent cardiovascular and cancer diseases and to have a non-pharmacological beneficial effect on body disorders and diseases.

Structure - lesson timetable:

  • 8:00 - 10:00 Self preparation of the presentation according to the assignment
  • 10:00 - 12: Presentation of prepared assignments by individual students (annotated presentations) in the classroom, possible visit to the examination room to demonstrate relevant examination methods
  • 12:00 -13:00 Self-study
Introductory text - introduction of the topic

Preventive lifestyle counselling is an undervalued activity by physicians, often considered trivial and without much effect. Yet the opposite is true; it is one of the most powerful and effective ways to reduce the risk of disease and positively influence health overall. However, quality is an essential criterion - any specific recommendation must be supported by adequate evidence within the EBD framework. It is therefore not possible to make recommendations based on subjective opinion alone.

It is also important that the recommendations in the context of individual counselling are also based on the patient's specific condition, i.e. based on knowledge of the individual's risk profile. This also means that adequate counselling must be preceded by 'diagnosis' in the form of a preventive examination. Its aim is not only to detect any incipient, i.e. pre-pathological, changes in the body, but above all to describe not only the state of the body, but also the lifestyle, in its individual parameters. On this basis, it is then possible to recommend individually optimal measures, "tailored" to the individual, generally based on lifestyle modification, and at the same time corresponding to the overall general recommendations, approved and substantiated.

Such counselling is significantly effective not only for primary prevention, i.e. preventing the onset of disease, but also for improving - enhancing the effects of other therapies (e.g. pharmacological), or for the possibility of reducing dosage (and side effects) while maintaining the therapeutic effect.

The overall content of the lesson corresponds to this scheme - in addition to the introductory information on the health consequences and the criteria for classification of the factor, both methodological procedures for examination and general recommendations are given. These should then be adapted according to the individual risk profile.


Instructions for compulsory tasks

During the first two hours of class (8:00-10:00), prepare a presentation on the assigned topic.

Stick to each narrowly-specific topic as it is exactly assigned. Do not expand it to a more general level, nor to a related but different topic (which someone else will have).

You may use the study materials to prepare your presentation - the teacher's slides embedded here in the study materials (you may use complete whole slides, or adapt them), or other sources (but only scientifically based, EBD).

Prepare your presentation as a powerpoint file and have it ready to present by 10::00.

At 10:00, we will meet in the seminar room (as scheduled), and you will be called upon individually to give a prepared short presentation (up to 10 minutes).

For this session, there are a total of 10 - assignments - topics covering selected important areas.

If more than one student is assigned the same topic, only one student will be invited to present, randomly selected by the teacher. Optimally, all 10 topics should be presented, but this is not strictly necessary (the teacher may select only some topics, and the group will probably not present all of them). 

Your presentation of the assigned topic should benefit your colleagues, be clear and concise, and cover the exact topic assigned.
